Evan - can't remember if you went with an aluminum block or iron block - with an iron block I think you will be around 2650 - 2700 lbs or so. With an aluminum block Rockbits weight sounds about right to me. your undercar exhaust might weigh a few more pounds but you will probably save a few pounds in wheel/tire weight.

I've got a cast iron BBM block. BBM lists their aluminum block at 125 lbs, and their cast iron block at 250 lbs.
